To all whom t may concern.'

Be it known that I, ERNEST M. KLUGK, a citizen of the United States, residing at Bualo, in the county of Erie and State of New York, have invented new and useful Improvements in Automobile-Radiators, of which the following is a specification.

This invention relates to improvements in radiators for automobiles and the like.

One of the features of the invention has reference to the construction of the cooling element which is'provided with a series of independent cooling sections, any one of which may be removed from the remainder of the radiator for repair or replacement without in any way disturbing the other sections or dismounting the radiator.

Another feature of the invention has ref erence to the peculiar oblique arrangement of the deflecting portions of the tins whereby a more etlicient and uniform cooling effect is produced.

The principal objects of the 'invention are to provide afradiator in which the cooling sections may be quickly removed and replaced, and inl which air is deflected tangentially to increase the cooling eect.

The invention also relates to certain details of construction which will be hereinafter described and claimed, reference being had to the accompanying drawings in which a preferred adaptation of the improved radiator is shown.

Figure 1 represents the improved radiator partially in' front elevation and partially in section, two vertical sections being taken through the radiator on different lines to show the internal construction. Fig. 2 is an end or edge elevation -of the improved radiator. Fig. 3 is an enlarged fragmentary section taken vertically on line a a, Fig. 1, through' the improved radiator. Fig. 4 is an enlarged transverse horizontal section through the tubes of one of the cooling sections of the radiator showing. a plan view of one of the fins. Fig. 5 is an enlarged side elevation of a fragment of one of the cooling sections of the radiator. Fig. 6 is an enlarged vertical section of a fragment of one of the fins on line b b, Fig. 4. Fig. 7 is an enlarged fragmentary horizontal section on line c c, Fig. 2, showing the manner of securing the end plate to the tie rods by'means of flanged collars, a transverse section also being shown through two of the tie rods.

In referring to the drawings in detail, like numerals designate like parts.

The adaptation of the improved radiator shown 1n Figs. 1, 2 and 3 consists of an upper tank 1, for the water or other cooling medium, a lower tank 2 for the water or` other cooling medium, and a series of independent cooling sections fitted in interposed position between the upper and lower tanks, said independent cooling sections being connected at their respective ends to said upper and lower tanks for the circulation therethrough of the water or other cooling medium. The cooling sections are removably attached at their respective upper and lower ends to the upper and lower tanks by means of curved connections which fasten to the front of the tanks so that the sections when unfastened may be easily and quickly removed by simply drawing them forward out of place in the radiator.

The cooling sections are identical in constructionso that one may be readily substituted for another, andl for this reason a detailed description of the construction of one of the sections will suhce for nall.

Each of the cooling sections comprises an upper hollow element or header 8, a lower hollow element or header 4, a series of vertical circulatingtubes 5 extending between and connecting said hollow elements, and a multiplicity of horizontal heat radiating tins 6 disposed at regular intervals and having openings through which the vertical tubes 5 pass. The upper hollow element or header of each section is substantially rectangular in cross-section, as shown in Fig. l, and practically constitutes a small supplementary upper chamber forthe cooling medium, which when the section is in place in the radiator is located directly beneath the upper tank 1. A tubular extension 7 curves forward4 and upward, and has its `upper end provided with an outwardly extending lange 8 through which screws 9 are adapted to be fitted to detachably secure the tubular extension to the upper tank 1, as shown in Figs. 2 and 3, particularly Fig. 3. A suitable packing 10 is fitted .between the upper end of the tubular extension 7 and the front face of the upper tank l to insure a tight joint` The `upper-tank 1 has on its front face a plurality of openings 11, each of which registers with the upper end of one of the tubular extensions 7. The lower hollow element or header 4 of each section is likewise substantially rectangular in crosssection, and constitutes a small supplementary lower chamber for the cooling element. Said lower hollow element 4 is provided with a curved tubular extension 12 which curves downward, and has its lower end detachably fastened to the front face of the lower tank 2. The front face of the lower tank 2 is likewise provided with a series of openings 13 which are equal in number to the cooling sections, and each of which is adapted to register with the lower end of one of the lowertubular extensions 12, as shown in Fig. 1.

The means for fastening the lower tubular extensions 12 to the lower tank 2 is slightly different from that employed in connection with the upper tubular extensions, heretofore described, a series of lock strips 14 being used, each of which is fastened to the front of the lower tank by a single screw 15. Each of the lock strips 14 has its respective ends lapping over the side margins or flanges of the lower tubular extensions 12, as shown in Fig. 1. However, if it is desired, either of the fastening means described may be used, or other suitablemeans may be employed in lieu thereof to detachably fasten the sections `in place.

The circulating tubes 5 are of oblong form in cross-section, as shown in Figs. 4 and 7 and extend in a straight vertical direction from the upper hollow element to the lower *hollow element, their upper ends being itted and secured in openings in the bottom wall of the upper hollow element, and their lower ends being tted and secured in openings in the top wall of the lower hollow element, as shown in Figs. 1 and`3. The hollow extensions or continuations 7 and 12 ot the hollow elements 0r headers have curved p openings therethrough of approximately the same area throughout, see Figs. 1 and 3, each of which gradually changes from a rectangular form at its merging point with the tubular header which is similar in size and 'shape to the opening in the tubular header to a circular form at its marginally anged rear end which is equal in diameter to the circular openings in the front of the water tanks. Furthermore, the gradual change from a rectangular'form to a .circular form prevents the formation of dead pools or quiet places for the circulating water, where freezing is most likely to occur in cold weather. All water in the radiator is thus kept constantly moving, and a substantially even temperature throughout the mass of water or other cooling duid is thus maintained.

The heat radiating line are preferably nionoeo as shown in Fig. 4, and a series of substantially triangular openings 17 which are located between the oblong openings, being arranged in straight rows between the straight rows of the oblong openings through which the tubes 5 pass. The triangular openings 17 are formed by cutting straight slits in the metal of the En, which extend in a direction transversely to the radiator, and straight slits which extend forward from the center of the transverse slits at a right angle to said transverse slits. The two projecting portions 18 and 19 formed by thus slitting the metal of the lin, are bent downward and away from each other sutilciently to extend or project in thepath of the air currents passing through the radiator when the automobile is traveling, and form air deecting portions. The air thus deflected, strikes against the adjacent surface of the next plate or passes through the openings therein, so that the air encounspect to the direction of the air currents which pass through the radiator, so that the air currents in passing through impinge on the surface 'of the said portions, and are thereby deflected diagonally downward and also laterally toward the conducting tubes 5, thus producing a better and more ecient cooling action.`

lt will be noted by referring to Figs. 4 and 5 that'the deflecting portions 18 and 19 progressively increase in size :from the front to the rear of the n. The advantage of this construction is that the air as it passes through the radiator, successively impinges on the dellecting portions, and is thus deflected toward all of the tubes, thereby producing a highly eflicient air cooling eect. The upper and lower tanks 1 and 2 are respectively provided with short `tubular connections 20 and 21, as shown in Figs. 2 and 3 for the attachment of pipes leading to the water jacket of the motor of the automobile. The radiator is provided with end plates 22 and 23, which are fitted flush with the ends of the upper and lower tanks 1 and 2. as shown in Fig. 1,and Serve to give a nished appearance to the ends of the radiator. These end plates are each supported from a pair of vertical tie rods 24 and 25 by means of upper and lower hanged collars 26 and 27. As two tie rods arenoso are employed at each end of the radiator, two upper and two lower collars are necessarily required, 'as shown in Figs. 1,'2 and 7. These collars are fastened to the plates by 'rivets and are fitted around the tie rods, as shown in Fig. 7. The upper and lower ends o the tie rods respectively pass through eyes in lugs 29 'and 30 which extend from the 'upper and lower tanks 1 and 2. Nuts 31 and 32 are screwed on the respective upper and lower ends of the rods and serve to tasten the component parts or elements of the radiator together. The radiator is yielding'Jl'y supported from the frame of the autom'o ie, vbeing balanced on springs mounted in brackets attached 'to the automobile frame. Two 'of these brackets are employed, 'one being located at 'each end of the radiator, and being fastened rigidly to the automobile frame by rivets or other suitable fastening's 33. In construction, each of these brackets has a horizontal member 34, the outer end portion of which is secured by arve't to the fraaie ci the automobile,

and two parallel vertical members 35 and 36, each of which is provided with upper and lower inwardly-'extending eyes 37 and 38 through which the 'tie rods loosely pass. Centrally located collars 39 are also provided through 'which the tie rods pass, said collars being fastened tothe tie rods by means of set screws 40, as shown in Fig. 1. Upper and lower springs 41 and "42 are respectively interposed 'between the central vcollars 39, and the upper and lower eyes 37 and 38. By this means; the radiator is yieldingly balanced against vertical movement in either direction, so that a large portion of the shockstransmitted to the frame of the automobile'is absorbed by the springs and is prevented from reaching the radiator. The upper tank 1 is provided with a filling tube 43 having a removable cap 44 which is secured in place by a set screw 45, as shown in Figs. 1 and 2.

The advantages of this improved radiator reside in the unique separable unit construction of the radiator, in the peculiar shape and formation ofthe cooling ns, and in the spring mounting of the radiator on the automobile frame. It will be noted that the cooling sections are absolutely independent and that any one of them may lie-removed by simply disconnecting it from the upper and lower tanks and drawing it forward out these coolin sections leak, it may be easily removed an the round openings in the upper and lower tanks easily closed by corks, thus enabling the operator to run the automobile until a place is reached where a proper repair may be made.
